Yes, I will.  I'll wait a bit to see whether any other arguments
surface in favor of weakening the license of GMP.

Yes, I thought I remembered something like that but couldn't
immediately find more details.  If such a library exists, we are
settled and can use GMP exclusively, no?  Anyone wanting to invoke the
exception in Guile's license can use the unrestricted substitute-GMP,
right?

Do you know more about this library?  Where could I find it?
